Two months ago, a 23-year-old patient with spinal cord injury was admitted to the Department of Functional Neurosurgery. We took a detailed medical history and found that the patient had fallen from the 2nd floor accidentally while repairing his house at home 3 years ago, and at that time, he developed complete loss of muscle strength in both lower legs, could not move, and lost sensation below the waist. At that time, after the L1~L3 vertebral body stabilization and compression surgery was performed under the emergency care of the hospital, he slowly gained some strength. At present, he can walk a few steps with a cane, but his sensory response is not sensitive, and the skin temperature of the lower limbs is colder than other normal parts. Decubitus ulcers appear on the skin due to reduced sensation and poor blood supply to the lower extremities. Sexual function was also not very good. The team decided to give the patient a spinal cord electrical stimulation procedure. The spinal cord electrical stimulation system consists of three components: electrodes implanted in the epidural space of the patient’s spinal cord, a stimulator that delivers electrical pulses implanted subcutaneously in the abdomen or buttocks, and an extension lead that connects the two. Intensive stimulation of the spinal cord nerves with residual function is attempted to restore function. The patient underwent the method within 2 weeks with the electrical stimulation installed. On the second day of installation, he turned on the device and experienced numbness of sensation in his lower extremities. The functional neurosurgeon team set the patient in detail to the appropriate voltage range for him and taught him to use the remote control device to adjust the voltage according to his feelings to stimulate the spinal nerves and lower extremity sensation. After 2 weeks, the patient’s sensation improved significantly and his skin temperature was much better than before. The family discussed and decided to install batteries and undergo spinal cord electrical stimulation surgery. In less than 2 months, the patient’s decubitus ulcers slowly diminished and his lower extremities gained strength, enabling him to walk up to 1,000 meters and sometimes off crutches. There was also significant improvement in sensory and sexual function. With the surgery and rehabilitation, the patient’s quality of life was significantly improved and his confidence in life was restored.
